Abstract

We report the chameleonic reactivity of two nonheme iron catalysts for olefin oxidation with H2O2 that switch from nearly exclusive cis-dihydroxylation of electron-poor olefins to the exclusive epoxidation of electron-rich olefins upon addition of acetic acid. This switching suggests a common precursor to the nucleophilic oxidant proposed to FeIII2-OOH and electrophilic oxidant proposed to FeV(O)(OAc), and reversible coordination of acetic acid as a switching pathway.
